    摘要： A brake cylinder of a motor vehicle, in particular a pneumatically actuatable brake cylinder of a commercial vehicle, includes a first housing part and a second housing part. An actuation tappet actuates a brake lever of a brake application device, which actuation tappet protrudes from a spring chamber of the first housing part. A membrane, which divides an interior bounded by the first housing part and the second housing part into a pressure chamber and the spring chamber, is provided, as well as a return spring for returning the actuation tappet from a braking position to a non-braking position. The return spring is arranged in a loaded manner between a housing bottom of the first housing part and a plate, which is arranged on the spring chamber side of the membrane and is connected to the actuation tappet. The return spring is provided with at least one elongation-measuring element.

    摘要： A torque measurement flexplate (20) includes a substantially planar body (54) which defines a plurality of circumferentially distributed axial through apertures (22), a radial web (24) extending between each pair of adjacent axial apertures (22). The flexplate (20) further defines a plurality of circumferentially distributed axial outer fastening holes (26) for attachment to an output member. The flexplate (20) includes a strain sensor (28) for measuring the shear strain field on the flexplate (20). The flexplate (20) defines a recess (30) in which the strain sensor (28) is located, the recess (30) being defined in an axial surface (32) of one of the radial webs (24) such that, in use, the sensor (28) lies at least proximate to one of the local neutral axes (34) relating to one of a plurality of unwanted strains (36) to which the flexplate (20) is subject in use.

    摘要： A low-cost, compact, high-precision axial force sensor is provided. The axial force sensor includes a pair of parallel pressing plates and a strain gauge sandwiched therebetween. The strain gauge includes a plurality of strain-sensitive resistive elements around its periphery, and is provided with a spacer that transmits a pressing force from the pressing plates to some of the strain-sensitive elements but blocks the pressing force to the rest of the strain-sensitive elements. The output signal of the strain-sensitive elements blocked from the pressing force provide an accurate baseline to compare the output signal of the strain-elements subjected to the pressing force. The spacer has a uniform pattern of open and closed portions. On the strain gauge, the strain-sensitive elements are provided at both the open and closed portions of the spacer.

    摘要： The present invention relates to a force transducer for measuring compression and/or tension forces, that comprises a rod-shaped deformation body with at least a front side (103), a rear side (104), a left side (105), a right side (106), an upper end face and a lower end face, as well as at least four strain transducers (117, 121), that are applied on the deformation body and configured and set-up for measuring a longitudinal strain and a transverse strain of the deformation body. A front elongate recess (109) is provided on the front side (103) in the area of an intersection point (S) between a central longitudinal axis and a central transverse axis (Q1) of the deformation body. Lying opposite the front elongate recess (109), a rear elongate recess (110) is provided on the rear side. At least a left upper indentation is provided above the central transverse axis (Q1) and a left lower indentation is provided below the central transverse axis (Q1) on the left side (105). Respectively lying opposite these indentations on the left side, at least a right upper indentation and a right lower indentation are provided on the right side (106). A ratio of a surface area of a material cross-section in a center plane extending orthogonally to the central longitudinal axis and including the central transverse axis (Q1), to a sum of a surface area of a first partial region of the material cross-section and a surface area of a second partial region of the material cross-section, is not smaller than 1.56 and not larger than 2.15.
